VACUUM FEED TANK.

Application filed January 3, 1925. Serial No. 367.

improved vacuum feed tank will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing forming a part of this application, in which:

Fig. I is a vertical section on a line corresponding to line'11 of Fig. VI.

Fig. II is a plan view.

Fig. III is .a fragmentary view partially in section on broken line 3-3 of Fig. I.

Fig. IV is a detail section on a line corresponding toline 44 of Fig. II.

Fig. V'is an enlarged detail section on a line corresponding to broken line 5-5 of Fig. II.

Fig. VI is a detail section on a line corresponding to line 66 of Fig. I.

In the drawing the sectional views are taken-looking in the direction of the little arrows at the ends of'the section lines and similar numerals of reference indicate similar parts throughout the several views.

Referring to the drawing, I provide a cylindrical tank 1 having a horizontal partition 2 therein providing a float chamber 3 and a discharge chamber 4. The discharge chamber is connected to the carburetor or the like by the pipe 5. The fuel orsupply connection for the float chamber is indicated at 6.

The suction connection 7 is connected to the float chamber through the'suction passage 8, a portion of this passage being vertical as shown in Fig. V and having a valve seat!) at its lower end. Within the chamber I mount a cylinder 10 provided with a plunger 11. This cylinder is connected to the suction passage by the passage 12, the passage 12 being controlled by the ball valve 13 disposed at the upper end of the vertical portion 9 of the suction passage.

The suction passage 8 is controlled by the valve 14 which has a tappet 15 coacting with the valve 13 to lift the valve 13 from its seat when the suction valve 14 is closed thereby opening the cylinder to the suction and consequently actuating the plunger.

The discharge passage from the float chamber to the discharge chamber comprises the valve casing 16 having a pair of ports 17 and the disk valve 18 having ports therein adapted to be brought into register with these ports 17. The valve 16 is supported in the valve casing for rotary and limited vertical movement as is indicated in Fig. I so that there is no likelihood of its binding or becoming wedged, the weight of the liquid in the float chamber tending to hold itto its seat.

The valve 18 is provided with a stem 19 which engages a socket in the coupling member 20 on the valve and projects through the top of the casing permitting limited longitudinal movement between the valve and the stem. On the upper end of the stem is an arm 21 which is connected by the link 22 to the plunger 11 so that when the plunger is actuated the valve is rotated to open the same.

The spring 23 connected to the link 22 and to a pin 24 depending from the head or cover 25 of the float chamber serves to re- .turn the valve to closed position and the plunger to its initial position.

The float is provided with a yoke 26 which is pivotally connected to a spring 27 the ends of the spring being mounted at 28 on the depending bosses 29 on the cover. This spring has a lost motion connection to the valve 14, the valve having a stem 30 arranged through the spring and provided with the tappet shoulder 31 on the collar 82. The float chamber is provided with a vent port 33 controlled by the downwardly seating valve 34 having a stem 35 arranged through this spring member 27 and having spaced tappets 36 at either side of the spring, thereby providing lost motion connection for the vent valve to the spring member.

With this arrangement, when the float rises it lifts the spring 27 and when the spring passes a predetermined pointit acts with a snap action to close the suction valve 1% and open the cylinder valve 13, also to open the vent valve The opening of the valve 13 actuates the plunger tnercbjv' opening the discharge valve and the vent valve being also opened permits the contents of the fluid chamber to discharge. As soon as the float lowers beyond a predetermined point the spring member 27 is again actuated to open the suction valve 1+: and close the valve 13;and to close the vent valve so that the float chamber is again subject; to the vacuum. The discharge chamber is provided with the usual vent tube 87.

\Vit-h the parts thus arranged I provide a structure in which the action is very positive. The discharge valve is easily operated and is not likely to become clog ed. At the same time it is not likely to leak the movementthereof tends to free the valve of any sediment and the weight of fluid tends to seal the valve. 7
